摘要： A piping article is provided that comprises a piping component comprising a piping body with an open end. The piping component is formed of an alloy comprising from about 12% to about 16% zinc, from about 0.5% to about 2.0% silicon, and a balance of copper (by weight). The alloy comprises an ultimate tensile strength of from about 200 N/mm2 to about 300 N/mm2, a yield strength of from about 75 N/mm2 to about 225 N/mm2, and an elongation of from about 15% to about 60%.

摘要： A piping component that includes (i) a piping body with an open end; and (ii) an alloy comprising (by weight percentage) 12% to 16.5% zinc, 0.265% to 1.6% silicon and sufficient copper so that the sum of the weight percentages of the zinc, silicon, and copper in the alloy is at least 99.7%. The alloy exhibits an elongation that is within a range of 60% to 70%. Additionally discloses is a piping component including (i) a piping body with an open end; and (ii) a cold worked alloy comprising (by weight percentage) 12% to 16.5% zinc, 0.265% to 1.8% silicon and sufficient copper so that the sum of the weight percentages of the zinc, silicon, and copper in the alloy is at least 99.7%. In embodiments, the weight percentage of the silicon in the alloys disclosed can be 0.5% to 1.6%, 0.5% to 1.8%, or 0.5% to 2.0%.
